frequently asked questions
-
Q: What are the requirements for the installation location of the JK80 Series pressure switch?
It is recommended to install it in an area with low vibration and small temperature variation, and keep it away from strong electromagnetic interference sources such as frequency converters and high-power motors. For harsh working conditions (e.g., humid, dusty environments), a vertical installation method (with the pressure connector facing downward) is required, and the inlet point should be sealed to prevent moisture intrusion. When installing or disassembling, use a wrench to turn the hexagonal (or flat square) structure at the connection; do not directly rotate the housing, as this may damage internal components. -
